New Location: Ravensberg Mountain

Located near Bad Sachsa, Niedersachsen (Lower Saxony) – a state that provides very few thundereggs compared to some of the others. These are a distinctive location, with beautiful flowbanding and thin bands of sometimes vivid red agate. I have now added a page of them on the gallery, and here are some of the best ones.


Three New and Unusual Richardson Ranch Locations

Here are three more specimens from Richardson Ranch that are not from any of the familiar beds.  As usual, there is only so much I can say about these and the tags consist of little more than rough guides to the area in which they are found.  Nevertheless, they provide some new ideas of just what that ranch is capable of producing.


First up is an absolute stunner, in my opinion – and also the most mysterious.  This was not from any of the hundred or so locations on the ranch, this was a ‘float egg’ – by which I mean a lost rock just lying on the ground, with all the mystery that entails. You can see this in the very brittle and fractured matrix. The colours here are rather different from anything I have seen before – indeed, this is one of the most beautiful matrixes I have ever seen from this area.


The above specimen is from a small deposit “On the Road to the Opal Bed” and it shows a very clear kinship with the Bed #1 etc. geology in the black splotches.


Lastly is a specimen with a matix that has little kinship with either the Priday type or the Bed #1 etc. type – a smooth brick-red stone that seems to have more in common with Brown Ranch or somewhere like that.  This comes from a small deposit “On the Road to the New Ledge Jasper Bed”

There are some more of these obscure Richardson locations still to polish, so keep an eye out for those in the future.

New Thundereggs from a New Country: China

Kind of like the old joke about the buses … you wait hours for one to turn up, then a bunch of them all come along at once!  China had been a bit of a blank of the Thunderegg map for a while, with the odd Fire Mountain specimen turning up VERY occasionally and nothing more.  But then things suddenly changed.  No less that four more locations suddenly appeared on the market, starting with Pujiang a year or so ago … Now, China is on the scene – and now I have got three of the five locations on the gallery as well.  The other two to follow.  Hopefully they will remain on the scene now because I can tell you, these can be stunning stones and further locations would be extremely exciting.

Some More Polish Rock Porn – And Something More Unusual.

I have just uploaded some interesting new specimens from Poland to the gallery – some of the greatest Thunderegg locations in the world!


This beautiful specimen is from the closed Nowy Kościół sub-location Wrzynka – one of the few specimens I actually have a bed name for. More striking is the very unusual matrix colour.  This is not typical of Wrzynka, or any other sub-location that I am aware of and the ghostly white gives it a very special feeling indeed.


Another Nowy Kościół specimen with a known sub-location – simply described as “The Wood on the Mountain“.  As you can see, a complex specimen with a much more familiar matrix.


Next up is something rather more unusual. This one is from the Owczarnia Hills, not far away from Sokolwiecz – presumably a wholly new location to me, which is exciting given how few locations Poland seems to possess.


And lastly, talking of Sokolwiecz, here is one – a substantial upgrade of the location and a fine example of the rich dark colours the area produces.

Lurking somewhere in my boxes is an excellent Gozdno specimen as well, still awaiting polishing.  Keep an eye out for that!

Two Newly Discovered Central Oregon Locations

Two new locations on the gallery, two fairly new locations in the Thunderegg world.  Both of these were discovered by Jason Hinkle with the help of Ed Pieters and both promise to be striking and rather special.

Paintbrush Bed is a simple and attractive location somewhat in the style of Wild Iris and others, sometimes showing some very nice staining of the matrix. The name comes from the huge thickets of Indian Paintbrush flowers among which the eggs were found.

Mountain View is a spectacular new discovery from 2014 in central Oregon. This is a very distinctive bed, marked by a very bright brick red matrix. The shape is often lenticular and the eggs are brittle and sometimes fragmented. The agate tends to be a quiet grey.

There will be more locations from Jefferson coming – including ones from with Richardson Ranch itself.  Keep an eye out for those.



A grand new arrival on the gallery from Saxony – the beautiful pale Tautendorf!  You can see some detail shots on the gallery itself here:


First Creek

I have finally uploaded three First Creek specimens to the Washington State section of the gallery.  This is an obscure but very interesting location producing relatively large eggs with a distinctly elongated and sometimes lens-shaped appearance.  The cores tend not to contain fancy agate, but a complex blend of minerals, sometimes very attractive in an earthy way.
